摘要
<p>Article access control method involves transmitting an user release code and a modification code to a releasing mechanism. The mechanism examines the user code and releases the code after positive examination of an article/release code modification device. The user code of a central processing unit is modified, such that the modification code becomes the user code of a next transmission, while modification code changes after the transmission in a certain manner.</p>
